Dear Itsik,

Thank you for your response and patience.

The presented object appears to be a serigraph on paper with the measurements of 25 x 30 cm. This motif has the title "Figures with Sunset" and appears to be signed with a signature in pen by Roy LICHTENSTEIN (1923-1997).
Works by this artist were recently offered and sold on the international auction market.
This piece is in good condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 200 to 300 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards,
Georg
